Talk:Flatworm
From Wikipedia, the free encyclopedia
Does anyone have examples of flatworms that have multiple openings to their guts (as is referred to in the page)? --Mperkins 03:44, 12 Dec 2003 (UTC)
This should probably be incorporated into an external link at some point. http://www.pbs.org/kcet/shapeoflife/video/tv_high.html?ep_hunt_explo2_mov_hi 06:30, 7 Jan 2005 (UTC)
- Done. But what exactly is the point of the video? Since when does Wikipedia link to videos?Dragix 16:07, 17 April 2006 (UTC)Dragix
In acoelomate flatworms, now thought to be unrelated to the Platyhelminthes... --unsigned comment
- What? Aren't they the same thing? I think this needs changing. --unsigned comment

New species of flatworm found: Imogine lateotentare. They have an interesting way of reproduction. http://www.smh.com.au/news/national/what-lurks-beneath--fleshsucking-sex-fiends/2006/01/20/1137734154394.html Since I'm not into this kinda stuff I'll leave it up to others if this actually needs mentioning and if so, how to go about it. --Mais

[edit] Pronunciation?
Is it pronounced "platyhelminteez" or "platyhelmintheez"? Twilight Realm 02:56, 19 April 2006 (UTC)
The latter. Cerealkiller13 05:09, 19 April 2006 (UTC)
[edit] Respiration
like all other animals, flatworms do take in oxygen
I may be wrong, but I thought adult cestodes (and many other gut-dwelling animals) were effectively anaerobic.
[edit] Notes on Flatworms
1) The classification presented is obsolete, and reflects relative importance to humans, not relationship among the worms. Modern classification of flatworms exclude Acoela and Xenoturbellida (both now phyla in their own right), while the remaining worms are grouped into roughly 14 high-order taxa. I'll see if I can find a good classification on the net.
2) The theory of biochemical memory in flatworms is long since abandoned - the results were misinterpreted. Contracting when hit by light is a natural response for flatworms to any sort of disturbance, and their increased propensity to do so after being fed "trained" (electro-shocked) specimens was due to the elevated stress hormone levels in the tissues of the "trained" worm. http://www.dur.ac.uk/robert.kentridge/bpp2mem1.html The worms were simply "more worried" due to higher stress hormone levels, and would react with alarm to weaker stimuli than non-stressed worms.
The flatworm "biochemical memory" is today abandoned as a scientific theory, but has almost become an urban myth, and is still often found in non-scientific contexts.
3) Yes, parasitic flatworms do as a rule use anaerobic respiration. This includes some forms which live in aerated environments such as the bloodstream.
[edit] Feeding
Does ANYONE know what flatworms eat? I've been trying for ages to find out, and I was a bit dissapointed to not find the answer under the feeding section. Egregius 15:31, 27 March 2007 (UTC)
